1. CERTIFICATE AND CONDITIONS OF WARRANTY
SOCOMEC warrants the SUPPLY against all proven defects or hidden defects in design and manufacture.
The period of warranty starts from the date of shipment and consists of 24 (twenty-four) months as from the date of
commissioning of the SUPPLY and shall not exceed 27 (twenty-seven) months from the date of the dispatch.
For all cases, the CUSTOMER shall not be entitled to enforce the warranty unless it shall have fully paid for the
SUPPLY.
The warranty of SOCOMEC shall be strictly limited to its SUPPLY and does not extend to the equipment within which
the SUPPLY is integrated nor to the performance of such equipment. SOCOMEC's liability shall be limited, in its
discretion, to the repair or replacement at its expense in its factory of all or part of the SUPPLY recognized as defec-
tive. As soon as the CUSTOMER has knowledge of the defect, it shall inform SOCOMEC in writing of the defects
which it claims affect the SUPPLY, and shall supply all evidence thereof and indicate the use and the conditions of
use of the SUPPLY. SOCOMEC reserves the right to modify the SUPPLY in order to satisfy the implementation of its
warranty. The repair, replacement or modification of all or part of the SUPPLY during the period of warranty shall not
have the effect of prolonging the duration thereof. Defective items replaced free of charge shall be made available to
SOCOMEC and shall become its property. Items invoiced as appropriate to the CUSTOMER shall be warranted 3
(three) months in normal conditions of use.
The warranty shall be excluded:
a) In the event that the defect is due to the material supplied by the CUSTOMER, or due to a design imposed by it.
b) In the event of damage or accident due to the transport or arising from the negligence, defective installation,
supervision or maintenance by the CUSTOMER or a third party.
c) In the event of use, installation or storage of the SUPPLY in abnormal conditions or conditions not in compliance
with recommendations of SOCOMEC.
d) If the CUSTOMER has carried out or has had carried out any changes, adjustments or repairs to the SUPPLY
without the express agreement of SOCOMEC.
e) In the event of damage arising from events of frustration or force majeure, or due to the fault of the CUSTOMER
or of a third party.
The warranty does not cover the replacement or repair of items which are due to normal wear and tear of the
SUPPLY.
SOCOMEC retains the full and exclusive ownership rights to this document. Only a personal entitlement to use the
document for the application indicated by SOCOMEC is granted to the recipient of this document. The reproduction,
modification, distribution of this document, either partially or wholly and in any manner, is strictly prohibited except
upon Socomec’s express prior written consent.

2. SAFETY STANDARDS
This user manual specifies installation and maintenance procedures, technical data and safety instructions for
SOCOMEC products. For further information visit the Socomec website: www.socomec.com.
NOTE!
Any work carried out on the equipment must be performed by skilled, qualified technicians.
NOTE!
Before carrying out any operations on the SUNSYS PCS2read the installation and operating
manual carefully. Keep this manual safe for future reference.
DANGER!
Failure to observe safety standards could result in fatal accidents or serious injury, and damage
equipment or the environment.
CAUTION!
If the unit is found to be damaged externally or internally, or any of the accessories are damaged
or missing, contact SOCOMEC. Do not operate the unit if it has suffered a violent mechanical
shock of any kind.
NOTE!
Install the unit in accordance with clearances in order to prevent access to handling devices and
guarantee sufficient ventilation (refer to 'Environmental requirements' chapter).
NOTE!
Only use accessories recommended or sold by the manufacturer.
NOTE!
When the equipment is transferred from a cold to a warm place wait approx. two hours before
putting the unit into operation.
NOTE!
When carrying out electrical installation, all standards applicable specified by the IEC and the
electricity supplier must be observed. All national standards applicable to batteries must be
observed. For further information refer to 'Technical specifications' chapter.
DANGER! LIVE DEVICE! RISK OF ELECTRIC SHOCK: SUNSYS PCS2is connected to three sepa-
rately protected power supplies:
1 DC cable - Battery power supply.
2 AC cable - Power from the mains network, supplied by the electricity company.
3 AC cable - Auxiliary power supply.
DANGER! RISK OF ELECTRIC SHOCK!
Before carrying out any operations on the unit (cleaning and maintenance performances,
connection of appliances, etc.) disconnect all power sources.
DANGER! LIVE DEVICE! RISK OF ELECTRIC SHOCK: Carry out the following steps before
system maintenance:
- Disconnect the batteries.
- Disconnect the AC power supplies.
- Disconnect the DC disconnection switches.
- Make sure the cable is fixed in position securely.
- Make sure the system cannot be restarted.
- Make sure the electricity supply (AC and DC voltages) has been disconnected.
- Cover or separate nearby live device units.
DANGER! RISK OF ELECTRIC SHOCK!
After disconnecting all power sources wait approx. 5 minutes for the complete discharge of the
unit.
CAUTION! RISK OF BURNS!: During operation the casing can reach high temperatures. Do not
touch the surfaces!

3. FOREWORD
Energy storage is the key solution to meeting the challenges of energy transition, using renewable energy and provid-
ing energy cost reductions for the following 4 main applications.
• Behind-the-Meter Energy Storage:
Reduce peak consumption and maximise PV energy self-consumption. SUNSYS PCS² (IM) can limit the impact
of increases in the electricity retail price by supplying the load to cut peak demand (peak shaving), maximising PV
energy self-consumption at building or community level. Any PV energy surplus is stored in the SUNSYS PCS² (IM)
battery system. This stored energy is used later to supply the load.
1
• PV plants:
Manage the intermittence of renewable energy production. SUNSYS PCS2(IM) ensures the production profile of an
intermittent renewable energy plant by limiting production to a predefined value, injecting energy to compensate for
solar variations, setting constant ramp-up or ramp-down.

• Grid support:
Meet the challenge of demand-response energy balance. When directly connected to the grid, SUNSYS PCS2(IM)
improves stability and management of grid operators thanks to voltage and frequency regulation, load shifting, peak
shaving and ancillary services for grid support.
3
• Microgrids:
Ensure energy availability and quality. The SUNSYS PCS² IM enables the microgrid to disconnect from the main grid
and be electrically autonomous thanks to local generation (PV, Wind, Diesel generators, etc.).
